Kalle Valo 5c9d0a2020 ath10k: add coredump_mask module parameter
For memory dump support (it consumes quite a lot of memory) we need to control
what is exactly stored to the crash dump. Add a module parameter call
coredump_mask to do that. It's a bit mask of these values:

enum ath10k_fw_crash_dump_type {
	ATH10K_FW_CRASH_DUMP_REGISTERS = 0,
	ATH10K_FW_CRASH_DUMP_CE_DATA = 1,

	ATH10K_FW_CRASH_DUMP_MAX,
};

For example, if we only want to store CE_DATA we would enable bit 2:

modprobe ath10k_core coredump_mask=0x2

Kalle Valo e48e9c429a Revert "ath10k: fix napi_poll budget overflow"
Thorsten reported on <fa6e3ee2-91b5-a54b-afe3-87f30aac7a48@leemhuis.info> that
commit c9353bf483 made ath10k unstable with QCA6174 on his Dell XPS13 (9360)
with an error message:

ath10k_pci 0000:3a:00.0: failed to extract amsdu: -11

It only seemed to happen with certain APs, not all, but when it happened the
only way to get ath10k working was to switch the wifi off and on with a hotkey.

As this commit made things even worse (a warning vs breaking the whole
connection) let's revert the commit for now and while the issue is being fixed.

Kalle Valo 005c3490e9 Revert "ath10k: Search SMBIOS for OEM board file extension"
This reverts commit f2593cb1b2.

Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:

ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin

The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

Kalle Valo 7be52c03bb ath10k: convert warning about non-existent OTP board id to debug message
Currently ath10k unncessarily warns about board id not available from OTP:

ath10k_pci 0000:02:00.0: htt-ver 2.1 wmi-op 5 htt-op 2 cal otp max-sta 128 raw 0 hwcrypto 1

But not all boards have the board id in OTP so this is not a problem and no
need to confuse the user with that info. So this can be safely changed to a
debug message.

Also fix grammar in the debug message.

Kalle Valo 1427228d58 ath10k: fix napi crash during rmmod when probe firmware fails
This fixes the below crash when ath10k probe firmware fails, NAPI polling tries
to access a rx ring resource which was never allocated. An easy way to
reproduce this is easy to remove all the firmware files, load ath10k modules
and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to call
napi_enable() from ath10k_pci_hif_start() so that it matches with
napi_disable() being called from ath10k_pci_hif_stop().

Big thanks to Mohammed Shafi Shajakhan who debugged this and provided first
version of the fix. In this patch I just fix the actual problem in pci.c
instead of having a workaround in core.c.

Kalle Valo 7ebf721d0d ath10k: refactor firmware images to struct ath10k_fw_components
To make it easier to share ath10k_core_fetch_board_data_api_n() with testmode.c
refactor all firmware components to struct ath10k_fw_components. This structure
will hold firmware related files, for example firmware-N.bin and board-N.bin.

For firmware-N.bin create a new struct ath10k_fw_file which contains the actual
firmware image as well as the parsed data from the image.

Modify ath10k_core_start() to take struct ath10k_fw_components() as an argument
which makes it possible in following patches to drop some ugly hacks from
testmode.c.

qca6174 otp binary seems to always return an error to the host, even if the

I was also considering making this hw specific flag but as this is strictly a
firmware issue it's best to handle this via a firmware feature flag so that it

Commit 8348db2984 ("ath10k: add ATH10K_FW_IE_HTT_OP_VERSION") broke QCA6174
receive side as the HTT ids from ATH10K_FW_HTT_OP_VERSION_MAIN don't have

Kalle Valo a58227ef69 ath10k: retrieve calibration data from file
A frequent request have been to be able to provide calibration data from a
file as some of the AP devices store the calibration data on an MTD partition.
This patchset adds support for that and also makes it easier to add Device Tree
support later on.

The calibration data is found by using the id string provided by dev_name()
using this format:

cal-<bus>-<id>.bin

With PCI the id string contains bus, slot and func values. For example for a
PCI device in bus 2 slot 0, ath10k will try to retrieve a calibration data from
a file:

/lib/firmware/ath10k/cal-pci-0000:02:00.0.bin

The calibration data sequence is:

1. Check with request_firmware() if there's a calibration file
   ("cal-<bus>-<id>.bin") on the filesystem for this device. If yes, use that. If
   not, goto 2

2. Check if otp.bin is able to successfully load the calibration data
   from OTP. If yes, use that. If not, goto 3.

4. Print an error message that no calibration data found and stop driver
   initialization for this device.
